Heterogeneous Nucleation and Grain Initiation on a Single Substrate
Metals, 2022 Recently, we have proposed a new framework for early stages solidification, in which heterogeneous nucleation and grain initiation have been treated as separate processes.

Effect of Heterogeneous Nucleation on Removal of Arsenic from Molten Steel by Rare Earth Addition
Metals, 2020 Cleanliness control is an eternal theme to improve the properties of steel products. With the increasing recycling rates of scrap steel, the removal and stabilization of residual elements have become a vital issue for improving the performance of steel ...

Heterogeneous Nucleation in and out of Pores
Physical Review Letters, 2006 We study the nucleation of a new thermodynamic phase in pores and find that the nucleation often proceeds via two steps: nucleation of pore filling, and nucleation out of the pore. These two rates have opposing dependencies on pore size, resulting in a pore size at which the nucleation rate of the new phase is maximal.

Sensitivity studies of dust ice nuclei effect on cirrus clouds with the Community Atmosphere Model CAM5 [PDF]
Atmospheric Chemistry and Physics, 2012 In this study the effect of dust aerosol on upper tropospheric cirrus clouds through heterogeneous ice nucleation is investigated in the Community Atmospheric Model version 5 (CAM5) with two ice nucleation parameterizations.

Molecular simulations reveal that heterogeneous ice nucleation occurs at higher temperatures in water under capillary tension [PDF]
Atmospheric Chemistry and Physics, 2023 Heterogeneous ice nucleation is thought to be the primary pathway for the formation of ice in mixed-phase clouds, with the number of active ice-nucleating particles (INPs) increasing rapidly with decreasing temperature.

Heterogeneous Ice Nucleation by Graphene Nanoparticles [PDF]
Scientific Reports, 2020 AbstractNanostructure, chemical composition and size distribution of aerosols have prime important effects on their efficiency in heterogeneous ice nucleation (HIN). The ice nucleation usually requires active sites in the aerosols in order to act as ice nuclei (IN).

Formation of ice particles through nucleation in the mesosphere [PDF]
Atmospheric Chemistry and Physics, 2022 Observations of polar mesospheric clouds have revealed the presence of solid ice particles in the upper mesosphere at high latitudes; however, their formation mechanism remains uncertain.

On the ice nucleation spectrum [PDF]
Atmospheric Chemistry and Physics, 2012 This work presents a novel formulation of the ice nucleation spectrum, i.e. the function relating the ice crystal concentration to cloud formation conditions and aerosol properties.
